Hello. I have a 69 Malibu 350. engine is in shop for overhaul. anyway, while mechanic had all of it torn down, I pulled numbers off all these parts. what do they all mean? car is a matching numbers 350.

Well google is your friend. Start by searching for Chevy casting #. It's a 350 block. Should be 4 bolt. As for VIN, wouldn't be the first time they stamped one wrong or mixed them up on the assembly line.

thanks for the info. what is T 13 and 37 TG 14? so, you have seen where one digit does not line up as rest of the vin? I also see these little stamp clock like stamps, with an arrow in the block, what are those? so this engine is a 2 bolt main.

I assume getting this rebuilt still adds value to the car as opposed to just doing a crate engine? this rebuild is taking forever, now they have to bore the block area where the crank goes, as it don't turn freely

yeah, the main area where the crank goes, the new crank didn't turn freely, so they sent to another machine shop, another 2 weeks as very few shops do the work and other engines they working on. they said this part would cost me another $200. they have now had my car since sept 22nd. this is sure a lengthly process.
